why does my Airconditioner stop working when the ck engine light comes on?

My 1992 Nissan Sentra has a very cold air conditioner but lately it has a strange problem. The air will stop cooling and the CK engine light comes on. then later the light goes off and the air blows cold again. I haven't hadthe ck engine codes tested yet. No one in this area does it on a car this old. I'm a 70 year old granny living on small SSA ck and can't afford much in repair cost so I'm relying on a friends help to fix it if he can. Thanks for any help

Thank you for your help. We purchased the sensor and the air still blows hot and the ck enjine light still on. I tried avanced auto and two others and they say they cannot test ck engine on a 1992 Nissan Sentra. :(
